IPC: F25J3/06
Filed: 1921-12-15
Abstract: 174,327. Soc. L'Air Liquide, Soc. Anon. pour l'Etude et l'Exploitation des ProcÚdes G. Claude. Jan. 21,1921, [Convention date]. Separating gaseous mixtures by liquefaction.- Hydrogen is separated from a mixture containing nitrogen, methane, and carbonic oxide such as is obtained by purifying coke oven or like gases, by subjecting the cold compressed mixture to temperatures progressively decreasing from the boiling-point of methane under atmospheric pressure to the freezing-point of nitrogen under atmospheric pressure, the liquid produced flowing in the reverse direction. The liquid may be collected in separate portions of different compositions. The final purification may be effected by expansion of the hydrogen produced with external work. Sufficient nitrogen and hydrogen may be ensured for effective operation by addition to the water gas of a proportion of nitrogen, combustion products, or hydrogen derived from the process. In the apparatus shown, the gas is fed by a pipe A through a cock B to the separating column C; impure methane collects in the bottom of the column and is delivered through a valved pipe F to about the middle, where it descends over plates G, G<1>, G<11>, and is rectified by the vapours rising through a nest of tubes D; nearly pure methane collects in the part H, and may be drawn off by the outlet K. The upper ends of the tubes D are set within a collector E<1> wherein a liquid consisting of mixed nitrogen and carbon monoxide is condensed, and which is fed through a valved pipe I to upper plates J, J', J<11> on which it is rectified by the vapours rising through a second nest of tubes D' to the top of the column, where a mixture of hydrogen and nitrogen collects. This mixture passes through a pipe P, liquefier Q, and pipe U to an expansion device X, the cooled exhaust from which passes around the upper ends of the tubes D', the hydrogen being drawn off by a pipe V and the liquid nitrogen passing by a cock X to the upper plates J. A pcrtion of the gas from the pipe A passes through a pipe R and the liquefier Q, and is delivered through a cock T' to the bottom of the column. Gases drawn off at the outlets K, K<1>, L may be collected as a mixture of nitrogen, carbon monoxide, and methane, and passed through a heat interchanger before being utilized, or the methane may be delivered to a separate compartment of the interchanger. At starting, the mixed gases may be passed through the pipe R in part to the expander N and through the pipe 0 to the jacket M of the column, and in part through pipe V, liquefier Q and pipe P to the top of the column; liquefaction gradually takes place in the lower portions; alternatively, the column may be filled through the cock X. The diameter of the upper part of the column and the number of tubes therein may be reduced.

Abstract: 431,382. Discharge lamps. SIEMENS ELECTRIC LAMPS & SUPPLIES, Ltd., Caxton House, Tothill Street, London, and ALDINGTON, J. N., c/o Siemens Electric Lamps & Supplies, Ltd., Dock Road, Preston. Dec. 6, 1933, No. 34333. [Class 39 (i)] Hot-cathode, high-pressure, mercury-vapour lamps with the electrodes close to the ends of the elongated container to avoid condensation of the filling at these ends have a filling of mercury and additional metals adding red rays, the filling being introduced in unvaporized form and being of such composition, and the lamp being operated at such a watts dissipation as compared with the internal capacity of the container, that the deficiency of red rays in the mercury spectrum is compensated, at least 2 per cent of the light passing through a filter which passes only light above 5800 Angstrom units. Cadmium, zinc and bismuth are referred to and fillings consisting of an amalgam of 2, 3 or 5 parts of mercury with 1 part of cadmium and 1 part of zinc are specified, either of the metals cadmium and zinc being replaceable by the other. The watts dissipation per c.c. of the container is of the order of at least 3.5 and the voltage drop in the discharge reaches À5 volts per mm. and is not less than 50 per cent of the mains voltage. The efficiency decreases with increasing proportions of the additional metals and when the efficiency drops to 60 per cent of that of the lamp filled only with mercury, the increase in blue light from the additional metals renders the increase in red light of little value. Each main electrode may comprise a barium silicate core in a tungsten spiral transverse to the axis of the tube and may be associated with an auxiliary electrode comprising a tungsten spiral of large thermal capacity. The auxiliary electrodes are connected together through a high resistance as described in Specification 410,558. The container contains neon at 5-10 mm. pressure together with argon at 20-100 microns and the sealing pip of the evacuating tube is made small and located slightly in front of an electrode to keep it hot and so reduce condensation of metal in the pip. The container is enclosed in an outer exhausted envelope. Details of the design of the lamp are specified. The Provisional Specification describes also lamps in which the filling contains 1 part of mercury to 4 of cadmium to 1 of zinc and in which the mercury, but not the other metals, is all vaporized in operation so that the colour of the light can be adjusted by varying the watts consumed.

Title: Container cushions and containers incorporating such cushions
IPC: B65D5/49
Filed: 1972-04-21
Abstract: 1391376 Cushioning for containers; packaging &c DEFENCE SECRETARY OF STATE FOR and EPS (RESEARCH & DEVELOPMENT) Ltd 19 July 1973 [21 April 1972] 34452/73 Headings B8P and B8C [Also in Division F2] A container cushion comprising a plurality of strips 1, 3 of at least partially polymeric, substantially self-restoring material, said strips being retained in a spaced apart condition, the arrangement being such that a compressive force first causes compression of one, or more, of said strips, and if increased above a predetermined value subsequently causes buckling of said one, or more, strips. The strips of material are formed from a material having a low "cushion factor" as defined in Specification 1,379,652. The strips, made, e.g. of expanded polyethylene or reconstituted polyurethane foam, are retained, e.g. by interlocking, adhesive or welding, or moulding, &c. in spaced "egg-box" structure, Fig. 5, by similar strips of the same, or other composition. Flat strips, Figs. 4, 5, or corrugated strips, Fig. 6, as described in the Specification of the above application, may be used. Alternatively strips, Fig. 7, of generally tapering cross-section, may be employed. If desired, strips of varying heights may be used in the same cushion, so that the highest strips receive the initial compressive force. Two cushions, formed of strips 1¢ inches wide can, advantageously, be stacked, one upon the other, with an intervening layer of the same material rather than using a single cushion formed of 3 inch wide strips. Cushion stiffness can be varied by changing the thickness of the strips and/or the spacing between the latter. In order to provide protection at low energy levels a layer of soft resilient material can be incorporated in the strips forming the cushion. Alternatively, the tapering strips, Fig. 7b, may be used. In the embodiment, as shown in Fig. 5, the ratio of width/thickness of the strips should not exceed about 8 since, at higher values, the strips do not readily return to their original thickness after impact.
